In case you need to demo some tool or work with any tool that sends webhooks, you can use ngrok to get the result.
There are other services available, but so it worked great and has features that improve your development experience.
Head to ngrok download page, and get the build. That page also describes how to install it (which is basically unzip an archive...).
How to use it
The basic format is
ngrok http 8080 which exposes port 8080 of your localhost to the web via the URLs provided in the ngrok console (you should see it once the command runs successfully, see below).
As you can see it provides HTTPS connection out of the box, which can be useful if the service you test only works with HTTPS.
You can also forward TCP requests with
ngrok tcp <port>.
This is one of the most useful features for me. Once you activated HTTP link, you can see all requests made via this link, and what's more importantly, you can replay the request in case you need to debug it. This is super helpful in case you are testing webhooks.
if you pass
--subdomain argument to the ngrok, you can actually use the same URL every time, as by default it generates a new URL every time. Again, it's helpful with webhooks as you don't need to manually change the webhook URL every time.
